Application filed March 8, 1917. Serial N 0. 153,504.

To all whom it may concern:

Be it known that I, GEORGES CHARBON- NEAUX, of- Le Magnou, par Aigrefeuille DAunis, Charente-Infrieure, France, have invented'a new anduseful Improvement in Electrolytic Cells, iwhich improvement is fullyset forth in the following specification.

Graphite anodes are frequently employed for the manufacture of variousproducts by electrolysis and'particularly for the manuw.

facture ofthe oxy en compounds of chlorin from chlorids. ther anodesformed of various alloys such as those having ferrosilicon for theirbase or cast metallic oxids are also employed.

In all cases the anodes pass into the elecrolyte from the top of thecell, or through holes formed in the lateral walls or in the bottom ofthe cell.

These arrangements have the following disadvantages:

As a considerable or is embedded in the walls of the cell, it is notutilized, thus uselessly increasing the cost of installation andmaintenance.

As the electrodes are in contact both with the electrolyte and with theliberated chlorinand also with its metal conductors ey must, especiallywhen of graphite undergo a suitable treatment to attacked by thecurrent. Moreover, as the electrodes are near together, it is usuallydifiicult to obtain good joints between them and the cell,

and this is the cause of great annoyance.

This invention relates to a novel arrangement of electrodes designed toovercome these troubles.

The invention is illustrated in the accompanying drawing, in whichFigure 1 is a horizontal section of a cell taken on the line AA of Fig.2, Fig. 2, is a vertical transverse section on the line B- B of Fig.

1, and Fig. 3 is a vertical transverse section showing a modification. av

The anode plates a andb are formlstl of graphite, metal, a metal alloyor a metallic oxid.

The left hand plates a alternate with the right hand plates 6 and theiroverlapping ends are pressed together to two terminals 0 i (i made fromone of the materials above portion of each anode avoid being mentionedterial.

The terminals 0 of pass through the wall of the cell and conductors e 7'located outside the bath.

The plates are pressed together by a suita le arrangement situatedoutside the bath for example, by means of two U irons with tighteningbolts above and or by means of bolts passing through the anodesthemselves and insulated therefrom by glass tubes, paint or someinsulating substance as illustrated bya tube B made, of glass, micanite,or any other insulating substance.

The plate 9 9 arranged between the anode plates.

In place of the plates shown in the drawing the electrodes may consistof rods, bars 01' the like. p

The terminals may be of prismatic or other shape; they are'two in numberora multiple of two and are sealed in the wall of the cell by anyconvenient means.

It is evident that the arrangement alone described although principallydevised for the manufacture of th chlorin is' applicable for themanufacture of various electrochemical products obtained by anodicoxidation.

The arrangement of electrodes herein described, has the followingadvantages:

he anodes do not pass through the walls of the cell, thus causing animportant economy in material forming the anodes and a great diminutionin the number of joints. As the terminals alone touch the current leadsthey also alone require a s ecial preparation for protection against theaction of the chlorin.

The joints are easy to make.

laims:

1. In an electrolytic cell of the character described, electrodesconsisting of alternating right and, left hand plates whose endsoverlap, teri'ninal members adapted to pass through the walls of thecell and associated with the overlapping ends of said plates and meansfor clamping said terminals and below the bath of the cathodes k '71,}are receive current from the e oxygen salts of overlap, terminal membersadapted to pass through the Walls of the cell and associated with theoverlapping ends of said plates and a clamping bolt passing through saidterminals and overlapping ends and a tube for insulating said bolt fromsaid plates and terminal.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
